DMZ advertiser and caching server question

[Saira]

Pretty sure i've done something wrong here, but i'm not thinking straight,
so i thought i'd ask to see if anyone out there can see my fatal flaw.
I have an internal DNS server in a child domain that has a forwarder to an
internal DNS server in a parent domain.The parent domain has a forwarder to
a caching only server on a DMZ (not a member of any domain), that has a root
hints file that allows the server to service internet requests from the
internal clients. this works well.

I have a web server in the same DMZ (again not a domain member). I have DNS
installed on this machine. It has a primary zone. it has two records, one
for the caching only DNS server and and one for itself.
When I try to ping the web server from the caching only server, I cannot. I
cannot see the website in the DMZ when i try to connect to it from the
internal domain.

Can anyone point me in the right direction? I am not sure how to finish off
this configuration.

Thanks
Saira

We need more details on your setup such as an ipconfig /all from the problem
machines (an unedited version - please do not make any changes). Check the
Event Viewer logs for any pertinent errors.

In addition to Todd's request, you mentioned a zone name in your web/DNS
server. What zone is this exactly? Is it the zone name for the website in
question?

Also, what purpose is DNS installed on this machine for? Is it hosting your
public domain name?

The reason I aske is due to the bare config info provided, for it appears
that the required zone and www record should be on the caching server, since
that is resolving queries for your internal network, and assuming so, for
the webserver itself, otherwise, I do not see how the caching server would
query the web/DNS server for the zone, provided. I'm assuming correctly the
zone in question exists on the web/DNS server.

Final note, your statement:

I have a web server in the same DMZ (again not a domain member). I
have DNS installed on this machine. It has a primary zone. it has two
records, one for the caching only DNS server and and one for itself.

Doesn't seem to indicate a www record created anywhere for this website,
once again, based on the assumption the zone in question is on the web/DNS
server.
